Lande-like formula for the g factors of hole-nanowire subband edges
D. Csontos, U. Zülicke, P. Brusheim +1
We have analyzed theoretically the Zeeman splitting of hole-quantum-wire subband edges. As is typical for any bound state, their g factor depends on both an intrinsic g factor of t…
Tailoring hole spin splitting and polarization in nanowires
D. Csontos, U. Zuelicke
Spin splitting in p-type semiconductor nanowires is strongly affected by the interplay between quantum confinement and spin-orbit coupling in the valence band. The latter's particu…
Large variations in the hole spin splitting of quantum-wire subband edges
D. Csontos, U. Zuelicke
We study Zeeman splitting of zone-center subband edges in a cylindrical hole wire subject to a magnetic field parallel to its axis. The g-factor turns out to fluctuate strongly as…
Crossover from diffusive to ballistic transport in semiconductor nanostructures
Dan Csontos, Sergio E. Ulloa
We present a detailed microscopic study of quasi-ballistic transport in deep submicron semiconductor channels. In particular, we study the crossover between the diffusive and balli…
Spin injection and accumulation in inhomogeneous semiconductors
Dan Csontos, Sergio E. Ulloa
We present a study of spin transport in charge and spin inhomogeneous semiconductor systems. In particular, we investigate the propagation of spin-polarized electrons through a bou…
